Evaporative cooling happens when moisture is added to the air through evaporation, which forces the air temperature to cool to its wet-bulb temperature, or sometimes to the point of saturation.

Evaporative cooling is a physical phenomenon in which evaporation of a liquid, typically into surrounding air, cools an object or a liquid in contact with it.

Evaporative cooling works by employing water's large enthalpy of vaporization.

Evaporative cooling was in vogue for aircraft engines in the 1930s, for example with the Beardmore Tornado airship engine.

Evaporative cooling is a physical phenomenon in which evaporation of a liquid, typically into surrounding air, cools an object or a liquid in contact with it.

Evaporative cooling works with the phase change of liquid into vapor and the latent heat of vaporization, but the self-cooling can uses a change from solid to liquid, and the latent heat of fusion to achieve the same result.

Evaporative cooling is a common form of cooling buildings for thermal comfort since it is relatively cheap and requires less energy than other forms of cooling.

Evaporative cooling also raises the internal humidity level significantly, which can cause problems such as lumpy table salt ; swelling and warping of wood paneling, doors and trim ; pianos going out of tune or suffering internal rusting, etc.

Evaporative cooling is especially well suited for climates where the air is hot and humidity is low.

Evaporative cooling is commonly used in cryogenic applications.

Evaporative cooling of ordinary helium forms a 1-K pot, which can cool to at least 1. 2 K. Evaporative cooling of helium-3 can provide temperatures below 300 mK.

Evaporative cooling is also the last cooling step in order to reach the ultra-low temperatures required for Bose – Einstein condensation ( BEC ).

Evaporative cooling performance is variable due to changes in external temperature and humidity level.

* Evaporative cooling increases humidity.

Evaporative cooling adds moisture, but in dry climates, dryness may improve thermal comfort at higher temperatures.

* Evaporative cooling simulation

* Evaporative cooling

Evaporative emissions are the result of gasoline vapors escaping from the vehicle's fuel system.

Evaporative air conditioning is also popular and well-suited to the southern ( temperate ) part of Australia.

* Evaporative cooler, which is a type of humidifier used in place of an air conditioner

* Evaporative: dry air blown over a reservoir will evaporate some of the water.

In addition, these BMW vehicles were certified as Partial Zero Emission Vehicles ( PZEV ): they meet the SULEV tailpipe emission standard, which is approximately 1 / 5 of the ULEV standard, and they conform to the Zero Evaporative Emissions requirements.

Evaporative media efficiency usually runs between 80 % to 90 %, and the evaporation efficiency drops very little over time.

* Evaporative coolers require a constant supply of water to wet the pads.

Because identified presolar stardust grains formed within outflowing and cooling gases from specific stellar nucleosynthesis sources, the isotopic composition of their elements is that of the stars and differs from the isotopic composition of solar-system matter as well as from the galactic average.

Cosmetically, the GXP differs from the other models with more aggressive bodywork including a different front clip, wheel well cooling vents on the front fenders, a different rear bumper, and twin-dual polished exhaust.

A closely related process, sublimation cooling differs from evaporative cooling in that a phase transition from solid to vapor, rather than liquid to vapor occurs.

Trigeneration differs from cogeneration in that the waste heat is used for both heating and cooling, typically in an absorption chiller.

It is apparent from the above and from experimental evidence that the cooling requirements for the anode of free burning arcs are large compared with those for the cathode.

It is absurd of course to say that that one exclamation estranged me from the family I considered my very own, but there it hangs, a cooling void that broke our close connection with each other.

Black antimony is formed upon rapid cooling of vapor derived from metallic antimony.

Rising magma also undergoes adiabatic cooling before eruption, particularly significant in the case of magmas that rise quickly from great depths such as kimberlites.

It enjoys a natural cooling from geophysical factors.

From 1944 to 1971, pump systems drew cooling water from the river and, after treating this water for use by the reactors, returned it to the river.

Crystals of BPO < sub > 4 </ sub > can also precipitate from the flowing glass on cooling ; these crystals are not readily etched in the standard reactive plasmas used to pattern oxides, and will result in circuit defects in integrated circuit manufacturing.

There are also several lake source cooling systems that are in operation on the lake, whereby cooler water is pumped from the depths of the lake, warmed, and circulated in a closed system back to the surface.

Instruments on Galileo detected a fireball which reached a peak temperature of about 24, 000 K, compared to the typical Jovian cloudtop temperature of about 130 K, before expanding and cooling rapidly to about 1500 K after 40 s. The plume from the fireball quickly reached a height of over 3, 000 km.

: This term is used both for conventional p – n diodes used to monitor temperature due to their varying forward voltage with temperature, and for Peltier heat pumps for thermoelectric heating and cooling .. Peltier heat pumps may be made from semiconductor, though they do not have any rectifying junctions, they use the differing behaviour of charge carriers in N and P type semiconductor to move heat.

The cooling system was of the free convection type assisted by a fan driven from a pulley mounted at the front end of the crank shaft.

Secondly, it is impossible for any device operating on a cycle to produce net work from a single temperature reservoir ; the production of net work requires flow of heat from a hotter reservoir to a colder reservoir, or a single expanding reservoir undergoing adiabatic cooling, which performs adiabatic work.

In order to make glass from materials with poor glass forming tendencies, novel techniques are used to increase cooling rate, or reduce crystal nucleation triggers.

By varying the number of particles added for heterogeneous nucleation and the rate of cooling in a hot-dip process, the spangle can be adjusted from an apparently uniform surface ( crystallites too small to see with the naked eye ) to grains several centimetres wide.

This was followed by the Little Ice Age, from the 13th or 14th century to the mid 19th century, which was a period of significant cooling, though not everywhere as severe as previous times during neoglaciation.

While humans have developed clothing and other means of keeping warm, the hair found on the head serves as primary sources of heat insulation and cooling ( when sweat evaporates from soaked hair ) as well as protection from ultra-violet radiation exposure.

Any heat that isn't translated into work is normally considered a waste product and is removed from the engine either by an air or liquid cooling system.

Furthermore, ice has numerous cultural applications, from ice cooling of drinks to winter sports and the art of ice sculpting.

This showed to him that granite formed from cooling of molten rock, not precipitation out of water as others at the time believed, and that the granite must be younger than the schists.

Because they become very hot, practically all machine guns fire from an open bolt, to permit air cooling from the breech between bursts.

Although H < sub > d </ sub > and S < sub > d </ sub > are not true equilibrium thermodynamic parameters and can depend on the cooling rate of a melt they can be found from available experimental data on viscosity of amorphous materials.
